The following are 30 code examples for showing how to use sklearn.datasets.load_boston().These examples are extracted from open source projects. Data mining and algorithms. Now let’s use the info() method which is useful for getting a quick description of the data, especially the total number of rows, the type of each attribute, and the number of non-zero values: Built-in datasets prove to be very useful when it comes to practicing ML algorithms and you are in need of some random, yet sensible data to apply the techniques and get your hands dirty. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example.
